From Wikipedia:
The theme of the design, the Historical Russian fight for freedom and independence, is expressed in eight large ceiling mosaics by Pavel Korin. Korin said that the inspiration came from Joseph Stalin's speech at the Moscow Parade of 1941, where he inspired the soldiers amid the catastrophic losses in the early period of World War II to remember the historical heroics of their Russian forefathers. The idea to design the art as a mosaic came from the Saint Sophia Cathedral in Kiev, where Korin saw that such artforms could last for eternity.
However the artistic decoration does not stop there, for in between each of the mosaics there are further ones made of gilded smalt depicting various weaponry and armour: one set is focused on ancient Russian equipment, a second on the Napoleonic era, the third on WWII. At the end of the platform is a bust of Vladimir Lenin under an arch decorated with gilt floral designs and the Coat of arms of the Soviet Union.
In the centre of the red granite covered platform are two passageways, surrounded by marble balustrades with escalators that descend into a lobby with a main escalator tunnel upwards to the Sokolnicheskaya Line's Komsomolskaya station. On the wall opposite the escalator is a large fluorescent mosaic, also of Pavel Korin, depicting the Order of Victory surrounded by red and green banners and Georgian colours.
